Problems setting serial port at 4800, 8 bits,EVEN, 2 stop bits

Rabbit

I need to set data parameters on port C :

4800 bps,
data word 8 bits
parity EVEN
stop bits 2

is that okay?

serCclose();
if (serCopen(4800))
{
serCdatabits(PARAM_8BIT);
serCparity(PARAM_EPARITY);
serCparity(PARAM_2STOP);
serCrdFlush();
}

Im asking because the device is not responding any message, and following the
sources seems like PARAM_2STOP and PARAM_EPARITY collisions on serial defnition
of port?

Thanks in advance!
